Using a Service Mesh to Improve Observability and Management
In this chapter, you will be introduced to the concept of a service mesh and see how its capabilities can be used to handle challenges in a system landscape of microservices, in areas including security, policy enforcement, resilience, and traffic management. A service mesh can also be used to provide observability, the capability to visualize how traffic flows between microservices.
A service mesh overlaps partly with the capabilities of Spring Cloud and Kubernetes that we learned about earlier in this book. But most of the functionality in a service mesh complements Spring Cloud and Kubernetes, as we will see in this chapter.
The following topics will be covered in this chapter:
- An introduction to the service mesh concept and Istio, a popular open source implementation
- Deploying Istio in Kubernetes
- Creating, observing, and securing a service mesh
- Ensuring that a service mesh is resilient...
